Electric High Pressure and High Temperature Power Station Gate
Valve (GAZ960Y)Product DescriptionZ960Y/Z961Y-250
Z960Y/Z961Y-320 The middle part of pressure
seal gate valve using pressure self-tightening structure,make
sure the valve has good sealing performance under high pressure and
high temperature conditions,usually,the sealing ring has two kinds
of material,one is low carbon steel,the other is flexible
graphite+SS 316,besides,the sealing surface is welding with hard
alloy,after the welding is finished,the thickness of metal
layer should be 3mm or more,therefore,it has advantages of
wear-resistant,temperature-resistant and anti-corrosion,greatly
prolong the service life.Both ends adopt welding structure,the
dimensions of welding groove can be customized on
clients' requirements.The medium can be high temperature and
high pressure water,steam,oil products and super-heated
steam.,etc,it's widely used for thermal power plant,petrochemical
industry,metallurgy and other industrial sectors.Product
FeaturesMain Features.The central connection adopt pressure
self-tightening structure.The disc and seat are welding with hard
alloy.High temperature creep resistance design.The material of stem
is precipitation hardening stainless steel by nitriding.Operating
device can be manual,gear,bevel gear and electric actuator.Product
